Comment 3 Alexander Tsoy 2018-08-14 06:02:42 UTC
This is a regression in mesa-18.2. Demos rendered just fine on the same system with mesa-18.1.
Comment 4 Alexander Tsoy 2018-08-14 06:59:34 UTC
Also both demos causes VM faults:

Can you try to record a renderdoc trace that reproduces the issue please?
Comment 6 Alexander Tsoy 2018-08-15 19:29:59 UTC
Not sure if I did it right:

Comment 7 Samuel Pitoiset 2018-08-16 12:19:27 UTC
Thanks for the trace, I can reproduce the problem. You might want to try two things:

1) RADV_DEBUG=nodcc fixes the rendering issue
2) RADV_DEBUG=nohiz seems to fix the VM faults

I'm working on.
Comment 8 Alexander Tsoy 2018-08-16 19:47:06 UTC
(In reply to Samuel Pitoiset from comment #7)
> 1) RADV_DEBUG=nodcc fixes the rendering issue
Yes. Also your patch [1] fixes it.

> 2) RADV_DEBUG=nohiz seems to fix the VM faults
I confirm that.

Comment 9 Samuel Pitoiset 2018-08-20 09:54:08 UTC
The rendering issue is fixed with https://cgit.freedesktop.org/mesa/mesa/commit/?id=0aacb5eab6120aa1410966d23101e16eea3fbcd7
Comment 10 Samuel Pitoiset 2018-12-11 21:03:39 UTC
This patch should fix the VM faults https://patchwork.freedesktop.org/series/53914/
